Description

Technical Field

[0001] This utility model relates to the field of soybean planting equipment technology, and more specifically, to a composite harvesting platform for soybean harvesting. Background Technology

[0002] As a widely cultivated and economically valuable grain and oil crop globally, the efficient advancement of mechanized harvesting is particularly crucial for soybeans. The soybean harvesting ram is a vital component of the soybean harvester, primarily used to mount the reel, conveyor auger, and other structures. During operation, the reel's rapid rotation lifts the soybean plants from the ground, and the conveyor auger then transports the plants to subsequent threshing and other processes.

[0003] However, the petioles of adjacent rows of soybean plants often intertwine, resembling a complex spider web. Existing harvesting platforms, with their limited functionality, struggle to effectively separate soybean plants from different rows. As a result, the harvesting platform frequently encounters entanglement problems, significantly impacting the final soybean yield and economic benefits. After pulling the soybean plants from the ground, some plants are too firmly rooted to be lifted by the rotation of the harvesting reel, leaving some plants in the soil and reducing the efficiency of soybean harvesting. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background art and to propose a composite harvesting platform for soybean harvesting.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A composite harvester for soybean harvesting includes a mounting frame, caster assemblies, a dividing assembly, and a cutter assembly. Two sets of caster assemblies are symmetrically and rotatably connected to the front end of the mounting frame. The two sets of caster assemblies are fixedly connected to the dividing assembly located in front of the mounting frame so that the dividing assembly can automatically adjust its angle when encountering undulating ground. A cutter assembly is provided behind the dividing assembly and is mounted on the mounting frame to cut soybean plants.

[0007] Furthermore, the above-mentioned solution includes an installation frame consisting of two support plates, a rear baffle, and a base plate that are fixedly connected to each other.

[0008] Furthermore, the caster assembly includes a mounting base, a pivot, a movable rod, a limiting seat, a base, a spring, and movable wheels. The mounting base is rotatably connected to the front end of the mounting frame via the pivot, and a movable rod is vertically slidably mounted on the mounting base. The top end of the movable rod is connected to the limiting seat above the mounting base, and the bottom end of the movable rod is connected to the base below the mounting base. The base and the mounting base are connected by a spring sleeved on the outside of the movable rod, and movable wheels are mounted on the base.

[0009] Furthermore, the above solution includes a mounting rod and dividing rods; the mounting rod is fixedly disposed between two mounting seats, and a number of dividing rods are spaced apart along the length of the mounting rod.

[0010] Furthermore, the above scheme includes a cone-shaped stalk to facilitate insertion between two rows of soybean plants.

[0011] Furthermore, the above solution involves raising the front end of the dividing stalk to reduce contact and compression of the pods, and to reduce the possibility of the dividing stalk coming into contact with the ground.

[0012] Furthermore, the above solution includes a sliding sleeve, a sliding rod, a saw blade, and a telescopic cylinder; there are two sliding sleeves symmetrically arranged on both sides of the mounting frame, and a sliding rod is slidably fitted inside the two sliding sleeves. A strip-shaped saw blade is installed on the sliding rod along its length, and one end of the sliding rod is connected to the telescopic cylinder set on the mounting frame.

[0013] Furthermore, the inner cavity of the sliding sleeve is rectangular so that the sliding rod will not rotate during the sliding process.

[0014] Furthermore, the saw blade is strip-shaped to improve the cutting effect.

[0015] Furthermore, in the above scheme, the telescopic cylinder is an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder.

[0016] Furthermore, the above solution includes an opening on the bottom surface of the mounting frame, where a soil sieve is installed to reduce the amount of broken soil entering the subsequent processing structure.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] In this invention, the linkage and contour-following design of the caster assembly and the dividing assembly greatly improves the harvester's adaptability to complex terrain. It can operate well on slopes or uneven ground. The dividing assembly can automatically adjust its angle, effectively solving the problem of difficulty in dividing soybeans caused by the crossing of petioles between two rows, and reducing the phenomenon of the harvester getting tangled. In addition, after the dividing assembly separates the soybean plants, the cutting assembly can accurately cut the soybean plants, avoiding the drawback that the rotation of the reel cannot lift them, thus improving the efficiency of soybean harvesting.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0025] See attached document Figure 1 -Appendix Figure 3 As shown, a composite harvester for soybean harvesting includes a mounting frame 1, caster assembly 2, dividing assembly 3, and cutter assembly 4. The mounting frame 1 consists of two support plates, a rear baffle, and a base plate that are fixedly connected to each other. Two sets of caster assemblies 2 are symmetrically and rotatably connected to the front end of the mounting frame 1. The two sets of caster assemblies 2 are fixedly connected to the dividing assembly 3 located in front of the mounting frame 1, so that the dividing assembly 3 can follow the shape of the ground during harvesting and can automatically adjust its angle when encountering undulating ground. The cutter assembly 4 is located behind the dividing assembly 3 and is mounted on the mounting frame 1 to cut soybean plants.

[0026] In the specific implementation of this utility model, during soybean harvesting, the harvester moves forward, causing the dividing platform to move accordingly. Since the caster assembly 2 is rotatable, when the harvesting platform moves across uneven ground, the caster assembly 2 can flexibly rotate with the undulations of the ground (for example, when encountering a small slope, the caster assembly 2 on the side closest to the slope will rotate upwards due to the rising terrain, causing the connected dividing assembly 3 to adjust its angle synchronously, thus achieving surface contouring). When the caster assembly 2 rotates due to the undulations of the ground, the dividing assembly 3 will automatically adjust its angle accordingly, ensuring that the dividing assembly 3 can always adapt to different terrains, effectively separating soybean plants in different rows and avoiding losses due to the cutting platform entanglement caused by improper dividing. After the dividing assembly 3 separates the soybean plants, the cutting blade assembly 4 can precisely cut the soybean plants. Finally, the reel pushes the cut soybean plants backwards, and the conveyor auger transports the plants to the subsequent processing structure, completing the harvest.

[0027] For the above scheme, please refer to the appendix. Figure 2 and attached Figure 3 As shown, the caster assembly 2 includes a mounting base 21, a pivot 22, a movable rod 23, a limiting seat 24, a base 25, a spring 26, and a caster wheel 27. The mounting base 21 is rotatably connected to the front end of the mounting frame 1 via the pivot 22, and the movable rod 23 is vertically slidably mounted on the mounting base 21. The top end of the movable rod 23 is connected to the limiting seat 24 above the mounting base 21, and the bottom end of the movable rod 23 is connected to the base 25 below the mounting base 21. The base 25 and the mounting base 21 are connected by a spring 26 sleeved on the outside of the movable rod 23, and the caster wheel 27 is mounted on the base 25.

[0028] In this design, the mounting base 21 is rotatably connected to the front end of the mounting frame 1 via a pivot 22. This allows the caster assembly 2 to rotate flexibly in the vertical direction, providing a basis for the harvester to adapt to different travel directions. The movable rod 23, which is vertically slidably mounted on the mounting base 21, works in conjunction with the limiting seat 24 to restrict the movable rod 23 to move only in the vertical direction. When the harvester travels on uneven ground, the moving wheel 27 encounters a bump or depression, and the base 25 moves with the up-and-down displacement of the moving wheel 27 (for example, when the moving wheel 27 encounters a bump on the ground and moves upward, the base 25 rises accordingly, at which time the spring 26 sleeved on the outside of the movable rod 23 is compressed, and the movable rod 23 slides upward within the mounting base 21; conversely, when the moving wheel 27 sinks into a depression, the spring 26 extends, and the movable rod 23, under the action of the spring 26, drives the base 25 and the moving wheel 27 to move downward, thereby achieving real-time response to ground undulations).

[0029] For the above scheme, please refer to the appendix. Figure 1 As shown, the dividing assembly 3 includes a mounting rod 31 and dividing rods 32; wherein, the mounting rod 31 is fixedly disposed between two mounting bases 21, and a plurality of dividing rods 32 are spaced apart along the length of the mounting rod 31.

[0030] In this design, the mounting rod 31 is fixed between two mounting seats 21, providing stable support and connection. This ensures that the entire dividing assembly 3 can be stably installed at the corresponding position on the harvesting platform, providing a reliable foundation for the effective operation of the dividing rods 32. When the harvester moves forward in the soybean field, these dividing rods 32, mounted on the mounting rod 31, can penetrate deep into the rows of soybean plants. Since there is a certain spacing between the soybean plants, the dividing rods 32 can separate soybean plants from different rows (for example, when the petioles of two rows of soybeans cross, the dividing rods 32 can insert into the crossing part by virtue of their spaced distribution, and separate the plants from different rows to avoid tangling on the harvesting platform).

[0031] Among them, the dividing stalk 32 has a conical structure with the front end curving upwards. The sharp front end of the conical dividing stalk 32 can easily insert itself between two rows of soybean plants like a wedge during the harvester's movement, guiding the soybean plants in different rows to the sides and avoiding entanglement with the header. At the same time, because its front end is curving upwards, it guides the soybean plants in a gentler way when parting them, reducing contact and compression of the pods and ensuring the integrity and yield of the soybean harvest. In addition, when encountering uneven ground, the upward-curving front end can reduce the possibility of the dividing stalk 32 coming into contact with the ground.

[0032] For the above scheme, please refer to the appendix. Figure 2 As shown, the cutter assembly 4 includes a sliding sleeve 41, a sliding rod 42, a saw blade 43, and a telescopic cylinder 45. There are two sliding sleeves 41 symmetrically arranged on both sides of the mounting frame 1. The inner cavity of the two sliding sleeves 41 is rectangular and a sliding rod 42 is slidably fitted inside them. A strip-shaped saw blade 43 is installed on the sliding rod 42 along its length direction, and one end of the sliding rod 42 is connected to the telescopic cylinder 45 arranged on the mounting frame 1, so that the telescopic cylinder 45 operates to drive the saw blade 43 to perform high-frequency reciprocating cutting action. The telescopic cylinder 45 is an electric cylinder, pneumatic cylinder, or hydraulic cylinder in the prior art.

[0033] In the design, two symmetrically arranged sliding sleeves 41 on both sides of the mounting frame 1 provide a stable sliding track for the sliding rod 42. The inner cavity of the sliding sleeve 41 is rectangular, and the way it cooperates with the sliding rod 42 ensures that the sliding rod 42 will not rotate during the sliding process, but can only make linear reciprocating motion along the direction of the rectangular inner cavity, ensuring the accuracy and stability of the cutting motion of the saw blade 43. When the telescopic cylinder 45 drives the sliding rod 42 to make reciprocating motion, the saw blade 43 moves back and forth between the soybean plants, using its sharp cutting edge to cut the soybean plants.

[0034] In the above scheme, considering the presence of loose soil on the soybean plants, to reduce the amount of loose soil entering the subsequent treatment structure, the following measures are taken, as per the appendix: Figure 4As shown, the bottom surface of the mounting frame 1 has an opening 11, and a soil sieve 5 is installed at the opening 11.

[0035] In this solution, as the harvester moves forward, after the cutter assembly 4 cuts the soybean plant, the soybean plant is conveyed to the subsequent processing structure. Because there is a soil sieve 5 at the bottom opening 11 of the mounting frame 1, the loose soil attached to the soybean plant will naturally fall and pass through the soil sieve 5 under the action of gravity. The mesh size of the soil sieve 5 is reasonably designed to allow loose soil to pass through while preventing the normal parts of the soybean plant and the pods from falling off, thus ensuring the purity of the soybean harvest, improving the harvest quality, and reducing the soybean quality problems that may be caused by loose soil mixing.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
